Opt-out of interest-based advertising

You can opt-out of having 3rd party ad networks select ads for your browser based on your online web browsing behavior, that FirstImpression.io might utilize in its ad placements. When you opt out, an opt out cookie (from firstimpression.io) will be stored in your web browser. FirstImpression.io will know the choice you have made when it sees your opt out cookie, and will use your choice to decide whether to exclude 3rd party ad networks that don’t support non-behavioral ad targeting or send a signal to supported 3rd party ad networks to only provide non-behavioral based advertising. If you block or delete the opt out cookie, you will not be opted out and will need to allow cookies from FirstImpression.io and renew your opt-out choice.


  • Blocked cookies: The opt out cookie may not work if your browser is configured to block third-party cookies.
    Deleting or protecting opt outs: If you delete your cookies, you will need to opt out again. There are browser plugins to help you preserve your opt out cookies. For more information, please visit http://www.aboutads.info/PMC.
  • Only this browser: The opt out only applies to the browser profile in which you set it. For example, if you set the opt out while using Firefox, but then use Chrome, the opt out will not be active in Chrome. To opt out in Chrome, you will need to repeat the opt out process. This is because the cookies cannot be read between different browsers or browser profiles.
  • The opt out does not block or delete cookies: It also does not prevent the use of cookies or other technologies for purposes other than selecting ads based on your interests as inferred by your online behavior. If you opt out, data may still be collected about your web browsing activities and you will still see advertising. Ads may be selected, for example, based on the content of the web page in which they are shown. If you wish to block or delete cookies altogether, you can use web browser settings to do so.
  • Learn More: To learn more about interest-based advertising, and to access the opt outs of other online advertising companies, visit the Network Advertising Initiative opt out page, the DAA’s WebChoices tool or the DAAC’s WebChoices tool.
